Leave your handprints on my ass, call it proof of purchase
Slap me, make me gag, f*ck me til it's hurtin'
Don't take it out, push it in and watch me work it
Leave your handprints on my ass, call it proof of purchase
You wanna work it out
You wanna do it now
So what you talkin' bout?
Come prove it to me now
Ware me out like a pair of Louboutins
Now whip it out, do me hard, let's get it going
Turn me out in the backseat of your car
The way you sweat really gets my juices flowing
Leave your handprints on my ass, call it proof of purchase
Slap me, make me gag, f*ck me til it's hurtin'
Don't take it out, push it in and watch me work it
Leave your handprints on my ass, call it proof of purchase
(This throat's lethal, my pussy's fire)
(Nasty, evil, your wet desire)
(Touch me, squeeze me, take me higher)
(Pump me up like you got a flat tire)
You wanna work it out
You wanna do it now
So what you talkin' bout?
Come prove it to me now
Call it proof of purchase
Call it proof of purchase
Call it proof of purchase
